core of this world conflicts with what Pyotr considers right — "you can violate laws of the society, but can't violate principles of the moral", "to be right is always an ordeal". Later Lukianenko supposes that the world of Geometers isn't free and really happy, due to both the hostile outer world and the kind inner world of the family are necessary to form a personality. Geometers can't be an ally for the Earth, only a new host — Pyotr understands it. A loose quote: "From point of view of inhabitants of the Motherland we are absolutely wrong. And we'll be oppressed — so quietly and insensibly that won't even notice that. Cosmodromes will empty, factories will stop — for instance, in order to rescue the wrecked ecology. Then Geometer will help us with their Mentors — the best in the world. For example, to introduce future generations to high knowledge. Will apply their bioengineering, beating our diseases and superfluous emotionality as well. What's the need of fire of emotions for those who strives for Friendship? One may even kill without fury and rage. A couple of generations will pass, by the way, as the Conclave wanted. And the Earth will become the new Motherland for those, who will be unable to understand this word really." Geometers' culture is a direct result of their history. Apparently, there were two intelligent lifeforms on the planet: the Geometers and those they called the Furry Ones (humanoids with fur covering their bodies). The Furry Ones were the more aggressive species and waged war on the Geometers. To fight them off, a Geometer doctor created a disease that completely wiped out the Furry Ones. The genocide horrified the Geometers, and they vowed to make any other race they encounter their friend (whether they want to or not). Some time later, a plague struck the Geometers but was cured when a doctor working with molds discovered antibiotics. The death toll was high, and the Geometer society was in disarray, allowing the Mentors to take full control and establish the "friend philosophy" as law. It has been suggested by some Geometer historians that the plague was engineered by the same doctor who stopped it at the behest of the Mentors, who were planning to use the disorder to take over. Such historians are silenced and placed in sanatoriums (i.e. prisons). Once space travel was discovered, the
